About the Airtac SCJ32 Standard Cylinder SCJ32X110-50
The SCJ32X110-50 is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides up to 50 mm of field-adjustable stroke reduction. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa, making it a compact yet capable actuator for light positioning tasks where the end-stop needs fine-tuning during commissioning or product changeovers.
This tie-rod cylinder features a PT1/8 port, an M10x1.25 rod thread, and a 21 mm air cushion for smooth deceleration. The body length A for the SCJ series is 182 mm. The screw adjusts the stroke end position only; it does not alter the cylinder's force output or speed. Operating pressure ranges from 0.15 to 1.0 MPa, with a standard temperature range of -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X110-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X110-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 110 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ32 Standard Cylinder SCJ32X110-50 Is Used
End-Stop Calibration
Fine-tune the retract or extend end position during machine commissioning without swapping cylinders, ideal for aligning sensor targets or mechanical stops on small assembly fixtures.
Wear Compensation
Adjust the stroke end to take up mechanical wear on gripper fingers or pressing tools, maintaining precise contact without reprogramming the controller.
Format Changeover
Quickly adapt a diverter gate or stop-pin stroke for different product sizes on a packaging line by turning the rear screw, reducing downtime between batches.
Is the Airtac SCJ32 Standard Cylinder SCJ32X110-50 the Right Cylinder?
Choose the SCJ32X110-50 when your application requires a stroke that can be manually shortened by up to 50 mm from its 110 mm nominal maximum. If you need a fixed, non-adjustable stroke, the standard SC32 series offers a simpler, more cost-effective solution. For a step up in force, the 40 mm bore SCJ provides 628 N of push at 0.5 MPa. A direct replacement must match the 32 mm bore, 110 mm nominal stroke, 50 mm adjustable range, PT port thread, and basic mounting style.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ32 Standard Cylinder SCJ32X110-50 FAQ
A screw in the rear cap limits the piston's return stroke. By turning the screw, you can shorten the effective stroke by up to 50 mm from the 110 mm nominal maximum. This sets a new mechanical end position, but does not change the cylinder's push (402 N) or pull (345 N) force at 0.5 MPa.
No. The SCJ32X110-50 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The air cushion only decelerates the piston at the end of stroke; it is not a locking or holding brake. For load holding without pressure, an external rod lock or pilot-operated check valve is required.
